SEP 12 RU1 MP1 takes more Memory than SEP 11 RU7 MP1
I have following situation.
Recently we have upgraded 2000 XEN-virtual systems XPSP3Pro from version 11 RU7 MP1 to version 12 MP1 RU1.
In version 11 we have been using Virus, Spyware and Basic Download Protection, Network Threat Protection, TruScan and Application Device Control. So that pretty much all except the Outlook, Notes and POP3 Scanner.
During the upgrade to 12 that was done using the SEPM Update without a reboot enforcement we kept the same settings and removed the Firewall. So installed is AV+AS+SONAR+IPS+Application Device Control+Tamper+Advanced Download Protection.
On a Saturday all the machines were rebooted and were all coming up with the version 12.
Since that time after the reboot when version 12 were present the memory consumption for all the 2000 systems has increased round about 23% consitent. Im not talking about a peak.
Im well aware of Citrix exclusions and I know we could try to remove features to get a different performance. But I would like to see why the Memory consumption has increased that much with the same policy as we dont use Insight Lookups etc. what is more or less a similar policy mapped from version 11 features.
Has anyone experienced the same issue?
